Benefits of Probe Data

Traffic information from probe data has the following benefits compared to the conventional information from fixed sensors:

Better coverage at lower cost: Fixed sensors are usually installed at important locations with high traffic volume due to their expensive cost. Cars with probe can go anywhere even in less congested or small roads.

More accurate data: Probe data reflects directly the travel time that the car has just travelled along that section of the road. While in conventional fixed sensors model, travel time is estimated from point speeds detected by sensors.
